Protect your above-ground pool from winter damage with our durable pool cover air pillow. Designed to absorb the expansion pressure of freezing water, this pool pillow prevents pool walls from cracking while reducing debris buildup. Made of extra-durable 0.4mm thick PVC—nearly three times thicker than standard options—this winterizing pillow resists leaks, tears, and deflation with patent-pending double-sealing embossing technology. Built for extreme weather, it withstands temperatures from −10°F to 180°F for reliable winter protection. The pool pillow features a dual Boston valve for quick inflation and reinforced grommets with a 50-foot rope for secure centering. As part of our Premium Sapphire Series, it meets USA-CPSIA safety standards, ensuring it is free from harmful chemicals and dangerous metals. Keep your pool safe, clean, and well-maintained all winter long with this essential winterization solution.
